Summary: Export of view op with dynamic input shape is broken when using tensors with a 0-dim. This fix removes symbolic use of static input size to fix this issue. Pull Request resolved: https://github.com/pytorch/pytorch/pull/43558 Reviewed By: ailzhang Differential Revision: D23965090 Pulled By: bzinodev fbshipit-source-id: 628e9d7ee5d53375f25052340ca6feabf7ba7c53
